I repeated this process until the mixture became sticky. I left it for 10mins until the dough had dried a little, & the consistency was smooth. I added more paint & continued mixing into the dough.

To check the dough had a glow, I moved the dough into a darker area of the kitchen to see if it radiated any light, & to my surprise it did!

To ‘charge’ the dough up, & prevent it from drying out, I placed it in an air tight Kilner jar & sat it on a windowsill in full sun. The sunlight caused the dough to glow - Hurrah! To add an extra ‘boost’ we shone a powerful torch on the dough, which made the dough to glow even brighter.

For the dough to maintain its glow it needs to sit for a few hours in direct light. If the dough is manipulated for a long period of time without much light it's unlikely to produce such a bright result. But once charged the effects are magical.

This really does work! I don't have the best camera, so the photos don't to it justice, but the dough does glow very bright.

What a great way to explore light, solar energy, power, sensory play, imagination & creativity.

I’m thinking it would be great fun for any parties coming up at the end of October & treat bags too! ;-)

How cool! I actually wrote "glow in the dark play dough" on my list of things to make this summer, but stopped and thought, "how on earth will I make it?!" How did I never see glow in the dark paint at ELC before?! SO brill. Thanks!

Wow! This is such a cool idea! I'm your newest follower, and have pointed my niece (newish mom) in your direction. I've also pinned this to my crafts board. Thanks so much for sharing your ingenuity!XoXoXoJoy

Anonymous - re: safe for infants, the ingredients I used for the play dough itself are all safe for little ones. If the play dough is consumed it won’t do any harm (just won’t taste v nice!) The glow in the dark paint I used was from Early Learning Centre (a UK children's store which stocks child friendly items including paint). This paint is non-toxic & suitable for little ones. I wouldn't advise using other paints/colourings unless they state they are suitable for this age range.

Although I've used homemade play dough with Minnie since she was 1yrs+ I probably wouldn't have used this one until she was older (3yrs. Hope this helps.

This is SO cool! I am your newest follower. I'd love for you to follow me back, if you want to =-) Also wanted to invite you to link up at TGIF Linky party - http://livinglifeintentionally.blogspot.com/search/label/Linkey%20Parties - I know my readers would LOVE this too!Beth =-)

LOVE this so much! Glow in the dark paint! What? ELC is our absolute favourite toy store but I've never seen glow in the dark paint there. We're in Australia, perhaps they don't stock it here. We MUST get some. Oh the possibilities!

Loved this, we tried it today over on our blog :)We also tried to make the play dough with vitamin-enriched water. We used 3 tablets with no glow, and then I added a tablet to a few teaspoons of water and that didn't glow, either. We got a vitamin with the same amount of Thiamine in it as the one you posted -- do you know what I could do to make the vitamin glow work? (Its a bit more accessible for us than glow-in-the-dark paint.)
